In order to respond to increased mail theft problems, the City has launched a citywide neighborhood mailbox program. Locking mailboxes will be available to SeaTac residents and businesses located within the City. Owners of single-family residences, duplexes, triplexes and business property owners that have individual mailboxes are eligible to participate in the program. Tenants may also participate with written permission from their landlord.
Locking mailboxes will be offered at the City’s cost of $108, with free installation. For those property owners with incomes below 50 percent of the median (based on HUD Income Guidelines for King County), the cost of the mailbox will be subsidized 50 percent by the City.
